Olga Tkacheva, Chief Geriatrician of the Ministry of Health of the Russian Federation, in an interview with Moscow 24, recalled the rules of conduct for people who have come into contact with patients with coronavirus infection. "First of all, of course, it is a two-week self-isolation for the duration of the maximum incubation period of infection. In addition, you can immediately take a coronavirus test to check if a person is already infected," Tkacheva said. She also recalled that after the mandatory quarantine has expired, you cannot just leave the house. You will have to take the coronavirus test again to make sure that the disease is not asymptomatic and the person is not a carrier of the infection. Moreover, the same rules apply to people who intersect with contact citizens. "We consider anyone who has come into contact with a COVID-19 patient as a potential patient. Therefore, people who have come into contact with such a person will also have to go through a two-week self-isolation and take a test," the geriatrician concluded. Previously, scientists have named the symptoms of a dangerous complication of the coronavirus. As a result of an excessive immune response to infection, a person can develop multisystem inflammatory syndrome. It is specified that its symptoms may include fever, abdominal pain, vomiting, skin rashes, fatigue, redness of the eyes, lips, tongue, diarrhea, and swelling of the extremities. In addition, scientists have identified a factor that dramatically increases the risk of hospitalization in case of coronavirus disease. They found that kidney disease has the greatest impact on the risk of hospitalization. In particular, in end-stage renal disease, the likelihood of going to the hospital is 11 times higher than the likelihood of a patient with COVID-19, but without kidney disease.
